Timezones and calendar

I use the calendar widget on the home screen and it has been useful thus far. I just returned from a trip to Europe to Singapore.

My device obviously updated the time (and my Pixel even had a notification saying “You're now in SGT time”).

Unfortunately the calendar widget is now broken. My events for tomorrow, Thursday, evening (local SGT time) show up for Friday night at midnight etc. Something obviously got stuck here and it's unclear how to fix it. I guess I can reboot and I'll try this, but.. it's a bug and it should. not. happen.

For some reason the bug tracker doesn't allow me to select “Android 17” as mu version, which is another issue altogether.
